Explanation

joules and kilowatt-hours are units of energy. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 joules = 2.77777778e-7 kilowatt-hours, and 1 kilowatt-hours = 3600000 joules. Because one kilowatt-hours represents a larger amount than one joules, the numeric value gets smaller in this direction.

How to convert joules to kilowatt-hours

  1. Enter the value in joules (J).
  2. Multiply it by 2.77777778e-7.
  3. The result is the equivalent value in kilowatt-hours (kWh).
  4. Round the result if needed.

Worked example
